IgY ELISA kits are assays designed to detect immunoglobulin Y, the major type of antibody produced in birds and reptiles. It is particularly prominent in chicken egg yolks. It contains three heavy domains and has no hinge region between the light and heavy chains. IgY is popular for use in the laboratory as its extraction is non-invasive, inexpensive, and can be harvested in large quantities. It does not activate the complement system or react with the rheumatoid factor in humans. Visit the supplier page for more information about detection target, range, and reactivity.
